Applications
Product Introduction
Energy Absorbing Bolt is made of smooth round bar with paddle configuration.It is an effective rock reinforcement system for underground roof support. If there is rock mass deformation, the paddle part will be worked as anchor points to bear the load and smooth section will absorb energy to prevent rock fall.
Features and Advantages
-After fully grouted in the bore hole, the paddle part will work as anchor points. If there is rock mass deformation, the paddle section will bear the load and the smooth section can move axially or radially without constraints and absorb energy to prevent rockfall.
-Kiruna wedge can be used for immediate support function. So that the wire mesh can be installed together with bolt.
-This Energy Absorbing Bolt is particularly suit for mines with large deformations in the rock mass, e.g. seismically active mines, rock burst or squeeze rock area.
-Product has been tested by CANMET,CANADA
